ACOUSTIC DEVICE FOR VEHICLE

PURPOSE:To obtain an uniform sound field which can generate profoundity and natural widespread feeling by supplying first output signals to right and left front speakers, supplying second output signals to right and left door speakers, and R+L signals to right and left rear speakers. CONSTITUTION:Right and left source signals (R and L) of an acoustic device 5 are applied to first and second reverberation generating circuits 6 to 9 and a mixing circuit 10. Further the first output signals generated by the first reverberation generating circuits 6 and 7 are respectively supplied to right and left front speakers R1 and L1, the second output signals generated by the second reverberation generating circuits 8 and 9 are respectively supplied to right and left door speakers R2 and L2, and the R+L signals are respectively supplied to right and left rear speakers R3 and L3. Thus the sound field with profoundity can be obtained, the sound field having the widespread felling in the lateral direction is generated, and the sound field positioned at the center can be obtained.
